Abstract

The structure consists of at least two channel systems (1,2). These are located above each other, in layers, which are separated by at least one card (3). Each system contains channels (4,5) with obstacles (10,11), which project alternately into the channels. The channels open into diagonally opposite connection and distribution channels (6,7,8,9), for even supply. USE/ADVANTAGE - Permeable structure esp. for heat exchangers. Heat exchange is mainly via thin foils. Obstacles improve heat transfer.

Description

Die Erfindung betrifft durchlässige Strukturen hergestellt aus geschnittenen Karten aus keramischem Material, insbesondere für Wärmetauscher.The invention relates to permeable structures made from cut Cards made of ceramic material, in particular for heat exchangers.

Unter Karten sind blattförmige Strukturen mit Durchbrüchen zu verstehen, die aus einer oder mehreren geschnittenen Folien bestehen bzw. aufgebaut sind.Cards are to be understood as sheet-shaped structures with openings that consist of one or more cut foils or are constructed.

Durchlässige Strukturen der genannten Art sind aus der DE-A 40 22 654 bekannt. Diese Strukturen weisen parallel zueinander verlaufende Lochreihen auf, zwischen denen Kanälen angeordnet sind, die in wechselnder Folge mit Kühlrippen versehen sind. Der Wärmeaustausch erfolgt über die Rippen, was lange Wege zur Folge hat. Hier will die Erfindung Abhilfe schaffen.Permeable structures of the type mentioned are known from DE-A 40 22 654 known. These structures have rows of holes running parallel to each other on, between which channels are arranged, which alternate with Cooling fins are provided. The heat exchange takes place via the fins, what long distances. The invention seeks to remedy this.

Die Erfindung löst die Aufgabe durch eine durchlässige Struktur, die dadurch gekennzeichnet ist, daß die Struktur aus Kanalsystemen besteht, die übereinander, durch eine Karte getrennt, in beliebig vielen Schichten angeordnet sind, wobei jedes Kanalsystem Kanäle mit Hindernissen aufweist, die wechselweise in die Kanäle hineinragen und die Kanäle in diagonal gegenüberliegende Anschluß- und Verteilerkanäle münden, über die die einzelnen Kanäle gleichmäßig ver- bzw. entsorgt werden.The invention solves the problem with a permeable structure is characterized in that the structure consists of channel systems which one above the other, separated by a card, arranged in any number of layers are, each channel system having channels with obstacles that alternately protrude into the channels and the channels diagonally opposite connection and distribution channels open, through which the individual channels are evenly supplied or disposed of.

Die Vorteile der Erfindung sind im wesentlichen darin zu sehen, daß der Wärmeaustausch vorwiegend über dünne Folien (kurze Wege) erfolgt. Darüberhinaus wird durch die Hindernisse in den Kanälen das Strömungsprofil neu gestaltet (verwirbelt), wodurch der Wärmeübergang zusätzlich verbessert wird.The advantages of the invention are essentially the fact that the Heat exchange mainly takes place via thin foils (short distances). In addition, the flow profile through the obstacles in the channels redesigned (swirled), which additionally improves the heat transfer becomes.

Im folgenden wird die Erfindung anhand von lediglich einen Ausführungsweg darstellender Zeichnungen näher erläutert. Es zeigt In the following, the invention will be explained using only one embodiment illustrative drawings explained in more detail. It shows  

Fig. 1 die Struktur in isometrischer Darstellung, teilweise geschnitten und Fig. 1 shows the structure in isometric view, partially cut and

Fig. 2 den Aufbau der Kanalsysteme von Fig. 1. Fig. 2 shows the structure of the channel systems of FIG. 1,.

Die durchlässige Struktur ist aus strukturierten Karten aus keramischen Material aufgebaut. Die Struktur kann durch Sägen, Fräsen, Drehen, Lasern, Stanzen und Flüssigkeitsstrahlschneiden in der Karte erzeugt werden. Die einzelnen Karten werden in bestimmter Reihenfolge aufeinander gestapelt, laminiert und zu einem Monolithen gebrannt. Dabei entstehen parallel verlaufende Kanalsysteme 1, 2 die übereinander durch jeweils eine Karte 3 getrennt in beliebig vielen Schichten angeordnet sind. Jedes Kanalsystem 1, 2 ist mit parallel zueinander verlaufenden Kanälen 4, 5 versehen. In die Kanäle 4, 5 ragen wechselweise Hindernisse 10, 11, durch die das strömende Medium umgelenkt und verwirbelt wird. Die Struktur weist ferner Anschluß - und Verteilerkanäle 6, 7, 8, 9 auf, in die die Kanäle 4, 5 münden. Über die Anschlußkanäle 6, 7 können die einzelnen Kanäle 4, 5 gleichmäßig versorgt und über die Verteilerkanäle 8, 9, die den Kanälen 6, 7 diagonal gegenüber angeordnet sind, entsorgt werden bzw. umgekehrt.The permeable structure is made up of structured cards made of ceramic material. The structure can be created in the card by sawing, milling, turning, lasering, punching and liquid jet cutting. The individual cards are stacked on top of one another in a specific order, laminated and burned into a monolith. This results in parallel channel systems 1 , 2, which are arranged one above the other by a card 3 in any number of layers. Each channel system 1 , 2 is provided with channels 4 , 5 running parallel to one another. Obstacles 10 , 11 alternately project into the channels 4 , 5 , through which the flowing medium is deflected and swirled. The structure also has connection and distribution channels 6 , 7 , 8 , 9 , into which the channels 4 , 5 open. The individual channels 4, 5 evenly supplied and via the distribution ducts 8, 9, which are the channels 6, 7 are arranged diagonally opposite disposed, or vice versa, can via the connecting channels 6. 7
